What was McCarthyism?

The following is from the website ML Today. It is all the more important to understand this important episode of our history given the current McCarthyite witch-hunt being carried out against anti-war and international solidarity activists.

Prof. Roger Keeran, a labor and policy studies coordinator at the Harry Van Arsdale Jr. Center for Labor Studies in New York, explains what McCarthyism was and was not during the 50’s. Dr. Keeran is author of the history, The Communist Party and the Autoworkers Unions.
